Answer:

isosceles

greater

Step-by-step explanation:

An isosceles triangle is a triangle that has two sides of equal length, so the lengths could be either 1, 1, 3 or 1, 3, 3. Since 1, 1, 3 is less likely, 1, 3, 3 is more likely to be the isosceles triangle.

The length of the third side is (3) in. The third side must be congruent to one of the other two sides because the triangle is (isosceles). The third side cannot measure 1 in. Because 1 + 1 is not (greater) than 3. So the third side must be measure (3) inch.

I hope this helps.

there is 25 people on a bus they pay R x each if there where 5 more people every body can pay R3 less how much is R x

Based on the given parameters, the value of Rx is R18

<h3>How to determine the value of Rx?</h3>

The given parameters are:

Number of people = 25

Amount paid = Rx

Additional people of 5 = Amount paid being R3 less

The total amount paid is calculated using:

Total amount = Number of people * Amount paid

Substitute the known values in the above equation

Total amount = 25 * x

Total amount = (25 + 5) * (x - 3)

Substitute Total amount = (25 + 5) * (x - 3) in Total amount = 25 * x

(25 + 5) * (x - 3) = 25 * x

Evaluate the sum

30 * (x - 3) = 25 * x

Evaluate the products

30x - 90 = 25x

Collect like terms

30x - 25x = 90

Evaluate the like terms

5x = 90

Divide both sides by 5

x = 18

Hence, the value of Rx is R18

Past records indicate that the probability of online retail orders

Tcecarenko [31]

Answer:

a) Mean = 1.6, standard deviation = 1.21

b) 18.87% probability that zero online retail orders will turn out to be fraudulent.

c) 32.82% probability that one online retail order will turn out to be fraudulent.

d) 48.31% probability that two or more online retail orders will turn out to be fraudulent.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

The mean of the binomial distribution is:

$E(X) = np$

The standard deviation of the binomial distribution is:

$\sqrt{V(X)} = \sqrt{np(1-p)}$

In this problem, we have that:

$p = 0.08, n = 20$

a. What are the mean and standard deviation of the number of online retail orders that turn out to be fraudulent?

Mean

$E(X) = np = 20*0.08 = 1.6$

Standard deviation

$\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{20*0.08*0.92} = 1.21$

b. What is the probability that zero online retail orders will turn out to be fraudulent?

This is P(X = 0).

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{20,0}.(0.08)^{0}.(0.92)^{20} = 0.1887$

18.87% probability that zero online retail orders will turn out to be fraudulent.

c. What is the probability that one online retail order will turn out to be fraudulent?

This is P(X = 1).

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 1) = C_{20,1}.(0.08)^{1}.(0.92)^{19} = 0.3282$

32.82% probability that one online retail order will turn out to be fraudulent.

d. What is the probability that two or more online retail orders will turn out to be fraudulent?

Either one or less is fraudulent, or two or more are. The sum of the probabilities of these events is decimal 1. So

$P(X \leq 1) + P(X \geq 2) = 1$

We want $P(X \geq 2)$

$P(X \geq 2) = 1 - P(X \leq 1)$

In which

$P(X \leq 1) = P(X = 0) + P(X = 1)$

From itens b and c

$P(X \leq 1) = 0.1887 + 0.3282 = 0.5169$

$P(X \geq 2) = 1 - P(X \leq 1) = 1 - 0.5169 = 0.4831$

48.31% probability that two or more online retail orders will turn out to be fraudulent.
